Artificial geothermal reservoirs in hot volcanic rock

Description: S>Some recent results from the Los Alamos program in which hydraulic fracturing is used for the recovery of geothermal energy are discussed. The location is about 4 kilometers west and south of the ring fault of the enormous Jemez Caldera in the northcentral part of New Mexico. It is shown that geothermal energy may be extracted from hot rock that does not contain circulating hot water or steam and is relatively impermeable. A fluid is pumped at high pressure into an isolated section of a wellb… more

Rocky Flats model 2030-1 container (AEC--AL USA/5332/BLF) safety analysis report for packaging (SARP)

Description: Division, Dow Chemical U.S.A., for shipping unirradiated fissile material in solid form. Components consist of a 30-gal steel drum, Celotex insulation, and stainless steel containment vessel(s) of 10-in. dia. A simple venting system prevents rtupture of the outer drum in the event of accidental fire. Approved material limits include 5 kg of plutonium or 11 kg of enriched uranium. Thermal decay energy is normally limited to 20 W. Results of extensive tests show the container will function effect… more

1-1/2-Loop Semiscale Isothermal Test Program: Program and System Description in Support of Experiment Data Reports.

Description: The isothermal test series is part of the Semiscale Blowdown and Emergency Core Cooling (ECC) Project conducted by Aerojet Nuclear Company for the U. S. Atomic Energy Commission. The test series consisted of ten blowdown tests and five hot-wall tests with emphasis on emergency core coolant delivery. The blowdown tests were conducted to investigate the effects of lower plenum geometry, heat transfer configuration, ECC injection location, downcomer gap size, and break size.

Characterization of actinide bearing soils: top sixty centimeters of 216-Z- 9 enclosed trench

Description: A program to examine the soil-actinide relationship in sediments from a disposal facility was initiated in March 1973. Initial work has been done using samples from the 216-Z-9 covered trench. Soil mounts were made of soil recovered from a core of an uncontaminated well drilled alongside Z-9 trench. The mounts were made by plastic-impregnating smaller, 1-in. diameter cores taken from the original 4-in. diameter cores. The uncontaminated mounts showed that the less than 30 mesh soil was composed… more

Resuspension of plutonium: a progress report

Description: Progress is reported for a research program on the resuspension in the atmosphere of plutonium fallout deposited on the earth surface. The long-range goal of the resuspension studies is to produce a set of equations which can be used to predict the timedependent average concentration of resuspended material downwind from a source of any geometrical configuration and soil sunface characteristics. The experiments are conducted at the Nevada Test Site where plutonium-high explosive tests were perf… more

Subterrene electrical heater design and morphology

Description: The design, construction, and testing of a variety of electrical heaters for small-diameter Subterrene penetrators has been pursued. The incompatibility of refractory materials at the required operating temperatures of ~2000 deg K and the large heat-flux requirements posed the most difflcult design problems. Heat fluxes of up to 2.0 MW/m/sup 2/ were obtained from pyrolytic-graphite radiant heattransfer elements and were as high as 2.5 MW/m/sup 2/ when this type of heater was combined with a lit… more

Fracture energy and strength of polymer impregnated cement

Description: The fracture energy, or effective surface energy of hardened cement paste and polymer-impregnated hardened cement paste, was measured by an analytical method. The fracture energy of polymer impregnated hardened cement paste is considerably higher than the unimpregnated paste (7.5 x 10/sup 4/ to 0.91 x 10/sup 4/ ergs/ cm/sup 2/). The increase appears to be entirely due to the polymer contribution. The results predict a factor of 5 improvement in the fracture strength of hardened cement paste upo… more

Multiple scattering enhancement of x rays

Description: A Monte Carlo calculation is described for the determination of the contribution of multiple scattering to x rays scattered at 90 deg in various thicknesses of beryllium and carbon plates. The plates are inclined at an angle of 45 deg to the incident radiation. The photon energy range considered is 1 keV to 100 keV. Scatterer thicknesses range from 0.0046 g/cm/sup 2/ to 1.204 g/ cm/sup 2/. Two sets of results are given: one from a formulation neglecting the polarization, the other including pol… more

Theory of pion scattering by nuclei II

Description: The Chew-Low theory is used to calculate the scattering of a pion by a nucleon inside nuclear matter. Together with the standard relation between refractive index and forward scattering, this yields the wave number of a pion inside nuclear matter. Singularities appearing in earlier theories are avoided. (auth)

Photomultiplier tube testing and analysis. Technological Spinoff Report

Description: An investigation was conducted to determine the effect of a wide operational temperature range on the output of a small photomultiplier tube (PMT). This PMT is similar to the RCA 8571 miniature PMT. A calculator based instrumentation system is described including programming techniques used to reduce and display data. Also described is a Light Instrumentation System with specially designed fiber optic light guides which supplies light to the PMT to allow measurement of the PMT output with respe… more

Technique for environmental decision making using quantified social and aesthetic values

Description: A four-phase study was designed for the evaluation of social, economic and environmental tradeoffs in the analysis of nuclear power plant siting options. The results of the first phase of this work are reported. This phase included: examination of environmental statements and guidelines and intervenors' statements to determine the aignificant criteria to be analyzed; development of a questionnaire with design options for two chosen sites; the answering of the questionnaire by environmentalists,… more

Determination of threshold velocities and correlation of high-frequency endurance limits for LMFBR heat-exchanger materials

Description: Jet impact erosion tests and high frequency fatigue tests were conducted for 2-1/4 Cr-1 Mo steel. Utilizing the relationship between the velocity of impact and number of impacts to produce visible erosion, the threshold velocities were determined as 220 and 140 fps at 10/sup 7/ and 10/sup 8/ cycles respectively. The relationship between the high frequency fatigue strength and the number of cycles to failure was determined at room temperature up to a maximum of 10/sup 9/ cycles. The high frequen… more

Guide to the acceptance criteria for radioisotopic heat sources

Description: During the development phases of heat source programs (the fabrication for design verification, engineering evaluation, etc.), heat sources and test capsules are often required prior to the formalization of specifications and drawings. Furthermore, there are also programs where the quantities and technology are such that a detailed and unique set of documentation is not justified. Consequently, this document is intended to be a general guide to the criteria applicable in evaluating the acceptab… more
